Using pedals in a dual mono ("Bi-Amp") set up.

[kaputsport]

I run a split setup. Here is the signal path:

Pedulla Rapture> A/B/Y pedal.

A: Boss LS-2
LS-2 Chain A: OC-2/Animato/Hamatoma/P+C/Mastotron/Return
LS-2 Chain B: FM4/Deep Impact/Muff/BSW/Return
LS-2 out into Peterson

Peterson into Marshall DBS 7200

A/B/Y Chain B: Marshall DBS 7400

7200 powers a 4x10
7400 powers a 1x15

One cable from the bass, always have clean on the bottom, effects on the top, and can double stack effects if need be. I might remove the LS-2 and just use the A/B/Y but the lack of clean through makes it tough.

I have a dual setup too.

My bass goes directly into the Lehle P-Split and the clean path finally into the Fender TBP-1 and into a 410. The other goes into some effects and finally into a 112.
I never had better basssound.

Some things already have changed, but basically it's like this: https://lh3.googleusercontent.com/-chQCNiawo58/TtOfhaJehaI/AAAAAAAAAV8/asOcPPAf1B8/s640/Foto0048.jpg
P-Split Direct Out --> Markbass Superbooster --> Tuner
P-Split second Out --> Markbass Supersynth --> Line6 M9 --> Volume Pedal
Both go then into a Crest 8200 Poweramp and into the cabs.

This way I'm able to mute both of the ways separately. This is so much fun! However, this setup is still pretty small. I just imagine it with two 810s... Power would be enough, I've got twice 1450W...

You put a pedal in one of the chains to would allow to correct the phase so they both match.

Silly question perhaps, but how would one know if there's a phase issue, and are you saying that sticking a pedal in one or both signal paths will automagically correct phasing (hence why I haven't knowingly had any problems)?

Some pedal when engaged flip the phase. I believe that's what he means. And it usually goes from a full sound to a very thin sound if it's out of phase I believe.

Correct, although it does get more technically complicated than that. Nearly all pedals alter the phase at least a little bit, plus some gain stages flip a 180. But this only becomes relevant when blending back in the original signal; and the amount that it is audible even then will vary quite a bit. When you can hear it, your tone sounds thin, or the lows sound weak.

If you coincidentally/unknowingly put another pedal that happens to flip the phase in line after ONE of the paths, then yes it can "automagically" solve the problem and you'd never know it.

I run two effect chains into two amps whenever I get the chance, for both bass and guitar gigs. Bigger, fatter, more complex sounds. One cleaner, one dirtier. Fun!

One of my favorite tricks it to run a wah pedal in only one of the chains.
